CAN/CSA-C22.2 NO. 257-06 (R2015)

1.1 This Standard specifies the electrical requirements for safe interconnection of inverter-based micro-distributed resource (micro-DR) systems to low-voltage systems connected to distribution systems. The output of these systems is limited to 600 V (nominal) or less (single or three phase).
1.2 Intentional islanding conditions and interconnection to secondary networks are not covered in this Standard. Note: Inverter types and operating modes are provided in Annex F.
